Hello,
I would like to ask advice. My colleague run into a problem, when he had
used TProcess to spawn other process. Because of fork nature, file
descriptors was copied into newly created process.
He found that for such cases CLOEXEC flag exists to be used when open file.
I found flag declared in various units inside fpc, but nowhere to be used.
So when I need to use it I need to make some own routine?

I have added it to the linux unit:
Const
O_CLOEXEC = $80000;
If you want to use it today, you'll need to add it to your own units
manually.

Or more generally do exists in fpc some other way how to deal with this
problem - to create new process but without copied file descriptors?
